British retail sales rebounded in January, official data has shown, with consumers buoyed by the removal of Brexit uncertainty according to analysts.

Sales by volume rallied 0.9% from the previous month, after falling in both November and December, the country's Office for National Statistics said in a statement.

That was the largest increase since March 2019 and beat expectations for a 0.7% gain.

Consumers were reassured by December's convincing election win for UK Prime Minister Boris Johnson, according to Paul Dales, economist at research consultancy Capital Economics.

Mr Johnson's Conservative party campaigned to "get Brexit done" - and Britain subsequently left the European Union on 31 January, dispelling long-running uncertainty over Brexit.

"January's retail sales figures showed that December's election result gave consumers the confidence to reopen their wallets," Dales said.

"The more recent flooding and effects of the coronavirus may hinder sales in February and March.

"Nonetheless, it still seems as though the economy turned a corner at the start of the year."

Britain left the EU on 31 January  but remains bound by its rules in a transition period that expires at the end of this year, as both sides aim to negotiate a new trading relationship.
